进入21世纪以来环境保护越来越受到世人的关注，在涂料工业领域，溶剂型涂料含有大量的挥发性有机溶剂(VOC)，在使用过程中排入大气，不仅破坏大气环境，危害人们健康，同时也浪费资源，浪费能源。目前，一般将水性涂料、粉末涂料、高固分涂料以及辐射固化涂料称为环保涂料。Since the beginning of the 21st century, environmental protection has attracted more and more attention from the world. In the coating industry, solvent-based coatings contain a large amount of volatile organic solvents (VOCs), which are discharged into the atmosphere during use, which not only damages the atmospheric environment, but also endangers people's health. At the same time, it also wastes resources and wastes energy. At present, water-based coatings, powder coatings, high-solid coatings and radiation-cured coatings are generally referred to as environmentally friendly coatings.
以水溶性树脂或水分散性树脂，包括合成聚合物乳液为基料的涂料均称为水性涂料。因此水性涂料也常称为水基涂料。合成聚合物乳液为基料的涂料均称为水性涂料。Coatings based on water-soluble resins or water-dispersible resins, including synthetic polymer emulsions, are called water-based coatings. Therefore, water-based coatings are also often referred to as water-based coatings. Coatings based on synthetic polymer emulsions are called water-based coatings.
